Micro-tweezers have been widely investigated because of their extensive applications in micro-fluidics technology, microsurgery and tissue-engineering. It has been reported that thermal actuation provides greater forces and easier control when compared to electrostatic micro actuation. In this paper, we discuss about the effects of Alumina as gripper on the operation of micro tweezers. The ...

Flexible electronics are temporarily affixed to a rigid carrier such as glass or silicon prior to device fabrication to facilitate robotic handling of the device, but also to allow optical lithography to stay within overlay design registration budget; without the rigid carrier, a freestanding flexible substrate such as polyimide would distort unacceptably during even minor temperature excursions ...

The objective of this work has been to realize a feasibility study of a cooling device for a SQUID sensor using liquid nitrogen flowing through micro channels. The design consists of an epoxy cylindrical vacuum vessel skewed by a silicon microchannel heat sink. The SQUID sensor is situated directly on top of the microchannel heat sink. The device is used at room temperature and should be able to ...

The rapid increase in power densities of integrated circuits has induced a significant interest in new reliable and high heat flux cooling technologies. The implication of such growth is the increased need for more efficient and more compact cooling mechanisms. Promising research has been conducted in the area of MEMS cooling devices, taking advantage of the increased heat transfer ...

Laser-driven micromachines using total internal reflection were developed by using two-photon microfabrication. The optical torque exerted on the micromachine was evaluated by COMSOL Multiphysics software. The laser-driven micromachines will be applied to lab-on-a-chip devices.

Previous works on MEMS actuated Fabry-Perot interferometer (FPI) highlighted promising results for flexible display applications. Three primary color pixels have indeed been obtained using both photolithography and Roll-to-Roll printing process with satisfying color purity and transmittance. However both of these processes are expensive and time-consuming for preparing micropatterns. For these ...

We have simulated a capacitive MEMS switch for application to Coplanar Waveguide (CPW) circuits using COMSOL Multiphysics. The switch configuration involves a pair of metal bridges over the CPW line designed for operation in the Ka - Band frequencies. It is shown that the operating frequency of the switch can be tuned by adjusting the gap between the two bridges. Estimation of the switch ...

In this paper we present the first design and simulation results of flying microids. Microids are a particular type of microrobots that have insect-like dexterity. Our initial investigation into the ability of microids to walk, run, jump, turn, carry loads, and walk upside-down was previously presented. Having the ability to fly greatly extends transportability. Although others have previously ...
